inputCustom Additional Argument

Good morning,

I would like to use pyip.inputCustom to check an input as normal, but I would also like to pass in an additional string to be used in the Exception if the input doesn't pass. I have not been able to figure out how to pass that additional argument into the function called as an argument in inputCustom.

Thanks!

Start at the pyip.inputCustom entry point and inspect how it invokes the user-supplied validation function and constructs exceptions. Determine how an additional string should reach that function and appear in the failure exception; done means the documented call works and the existing inputCustom behavior remains intact.
